National‐scale mapping of potential floral resources for honeybees and native pollinators in New Zealand

open access: yesEcological Applications, Volume 35, Issue 3, April 2025.
Abstract Floral resources are important food resources for pollinators. These resources are produced in different quantities depending on land cover and plant species composition, and the quantity of production varies seasonally. As such, land use change and management of natural resources can have substantial impacts on conservation through resource ...

An integrative framework reveals widespread gene flow during the early radiation of oaks and relatives in Quercoideae (Fagaceae)

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 4, Page 1119-1141, April 2025.
Multiple lines of evidence from phylogenomics, paleontology, biogeography, and ecology support the occurrence of widespread ancient reticulations between major lineages of Quercus and relatives in Quercoideae (Fagaceae) during the Early to Middle Eocene in North America and Eurasia.

EARLY DEVELOPMENT OF NOTHOFAGUS (NOTHOFAGACEAE) SPECIES FROM THE SUBANTARCTIC FOREST UNDER EXPERIMENTAL CONDITIONS OF LIGHT, SUBSTRATE AND ECOLOGICAL INTERACTION

open access: yesCerne, 2018
The entry of trees into a community is an irregular process often constrained by species interactions and regeneration niche. We experimentally examined the effect of light intensity (high, medium and low), substrate type (mineral and cover with litter ...

Review of phlegmacioid Cortinariaceae (Agaricales) in New Zealand

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 1, Page 78-107, March 2025.
ABSTRACT We review the diversity of phlegmacioid (Cortinariaceae) taxa in New Zealand as well as in other parts of the Southern Hemisphere. Using a 4‐locus molecular phylogeny, it is shown that these taxa are represented in six of the ten recently recognised genera of Cortinariaceae.

Low Richness of Invasive Non‐Native Plants in New Zealand Indigenous Forests May Not Reflect Low Impact

open access: yesDiversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Identifying habitats vulnerable to plant invasions is essential for developing efficient management programmes. We assessed trends in richness and cover of non‐native plants in indigenous shrublands and forests across New Zealand. We investigated whether species classed as invasive species exhibited higher levels of plant invasion than ...

Ecological restoration principes relative to Nothofagus pumilio (Poepp. & Endl.) Krasser (Nothofagaceae) forest restoration [PDF]

open access: yesAnales del Instituto de la Patagonia, 2015
r Leaf surfaces are arranged in forested ecosystems so that solar radiation is effectively captured. In other words, the potential for photosynthesis is maximized as a function of plant community structure. In Nothofagus pumilio forest, tree crowns are densely branched and contain abundant, closely placed, small leaves that flutter on stout, subsessile
